A Study of Rubisco through Western Blotting and Tissue Printing Techniques

We describe a laboratory exercise developed for a cell biology course for second-year undergraduate biology majors. It was designed to introduce undergraduates to the basic molecular biology techniques of Western blotting and immunodetection coupled with the technique of tissue printing in detecting the presence, relative abundance, and distribution of ribulose-1,5-bisphosphate carboxylase in various plant materials. Pre- and postlab surveys indicated significant postlab gains in student understanding of all three lab techniques and relevant lecture topics. Additional postlab survey questions on student perception of the lab modules suggested that the laboratory exercises successfully met a series of pedagogical goals set by the instructors. The combination of these techniques provided a basis for quantitative and qualitative (visual) analysis of a biologically important enzyme and can be applied or modified readily to study other proteins and biological molecules in lab exercises for an introductory cell biology course or molecular biology course.     

Dimensions of student success: a framework for defining and evaluating support for learning in higher education

ABSTRACT

The capabilities students need for success during and beyond higher education extend far beyond specific discipline skills to include the development of productive mindsets, the management of life circumstances and the way they relate to others and identify with their profession. The provision of support for these capabilities at university can be both diverse in scope and diffuse in delivery. Consequently, the development of streamlined and integrated evaluation strategies to measure the extent to which these capabilities are being successfully delivered can be challenging. This paper describes how one Australian university used a collaborative process to design an evaluation framework for student learning services. The framework, a first for this university, represents the breadth of student support, including a typology of support for learning: connectedness, mindsets, self-management, professional identity and academic capabilities. These terms, coined as dimensions, form the scaffold of university-wide delivery of support for learning initiatives.     

Teaching and Learning Regimes: Implicit theories and recurrent practices in the enhancement of teaching and learning through educational development programmes

This paper uses the concept of teaching and learning regimes (TLRs) to help explore a set of questions about why some academic staff in universities thrive on and benefit from accredited programmes designed to improve HE learning and teaching practices ("educational development programmes") whilst others experience periods of resistance or some drop out altogether. "TLR" is a shorthand term for a constellation of rules, assumptions, practices and relationships related to teaching and learning issues in higher education. These include aspects of the following salient to teaching and learning, each of which we elaborate and illustrate in the paper: identities in interaction, power relations, codes of signification, tacit assumptions, rules of appropriateness, recurrent practices, discursive repertoires, implicit theories of learning and of teaching. The argument presented here is that academic staff on educational development programmes ("participants") bring to programmes sets of assumptions and practices rooted in TLRs. Educational development programmes themselves instantiate TLRs which may be more, or less, compatible with those of individual participants. Where there are incongruities between the two they need not be fatal if participants are able to, or are encouraged to, surface and reflect on previously tacit assumptions embedded in their TLRs. Similarly, there may not be a problem if participants are able to exercise discretion over the application of aspects of different regimes; applying them in different contexts as appropriate. Evidence from participants' writing, participant observation, secondary sources and data from eight interviews inform the paper and form the basis for illustrative vignettes.

On ‘Politics,Markets, and American Schools‘

This paper traces the trajectory of New Labour education policy since the formation of the first New Labour government in 1997. During that time the policy discourse has moved from a position of individualized school improvement through competition, to one where there is an emphasis on ‘partnership’ and ‘collaboration’ as key mechanisms for improvement. We note, however, that ‘specialism’, ‘diversity’ and ‘choice’ are still key components of policy and that ‘partnership’ often denotes a deficit model, with more successful schools supporting (or in some cases taking over) less successful ones. Although there are the beginnings of a recognition that social class and social deprivation are factors which make achievement at school more problematic, generally New Labour policy has not attempted to alleviate the tendency to social polarization which has emerged as a result of school choice policies.     

Re-Discovering a Roman Wall Painting at Harvard: New Research on a Fragment from the Villa at Boscotrecase

ABSTRACT

This article presents historical and scientific analysis, as well as the conservation treatment of a newly rediscovered Roman wall painting fragment, now in the collection of the Harvard Art Museums. Although the piece has not previously been published, it was among a group of fragments removed from a Roman villa near Boscotrecase in southern Italy, an area that has been key to the study of Roman wall painting and other decoration. Technical imaging confirms the use of painting techniques consistent with other high-quality paintings in the area. Materials analysis revealed a palette consistent with published findings of Roman wall paintings, including abundant use of Egyptian blue and green earth. Of interest was the use of Egyptian blue as an optical brightener in select white passages. Despite the high quality of the painting, no cinnabar was present, and all red passages were achieved using hematite. Multiple different white minerals were identified including calcite, aragonite, and gypsum. The widespread presence of gypsum is unusual and may point to alteration.
